Double Butterfly is part of a series of several indoor metal mobiles designed by Joel Hotchkiss. This design is exactly the same as the single Butterfly design, but with an additional butterfly to create a set of mates. Made of formed brass rod and lacquered copper, these animated botanical insects create an intimate relationship between the viewer and the art. Signed and dated by the artist. Ready to hang, no assembly required. Joel Hotchkiss has been designing contemporary kinetic art and mobiles since 1976. His work has been sold in numerous museum stores including the Guggenheim, San Francisco Museum of Modern Art and the Art Institute of Chicago.
